Man blows up his house with flammable expanding foam trying to fill mouse holes
A Stockport man had a nasty shock when the he tried to fill mouse holes up in his boiler room, the foam filler he was using was flammable. The man wasn’t badly hurt only singed, but I bet he got a right old shock and thought the mice were using napalm against him..
Expanding foam has its uses when filling holes but it is of limited use for mice and rats. It will slow the mice and rats down but it wont stop them. It will also give you an indication that they are still active when you see the piles of chewed foam around the hole.
